推荐答案

在运输过程中无法对其进行修改，但可以在中间建造一个人.

这将位于客户端和服务器之间.

客户端将数据传输给中间的人，中间的人在将数据发送到服务器时重复/修改数据.

响应也会发生同样的事情.从客户端和服务器的角度来看，没有任何变化，因此可以随时将其删除.

您可以使用NetworkStream在.Net中构建一个简单的网络中继器.

You can''t modify it in transit but you could build a man in the middle.

This would sit between the client and the server.

The client transmits to the man in the middle, the man in the middle repeats/modifies the data as its sent to the server.

Same thing happens with the response. From both a client and server point of view nothing changes so it can be removed at any point.

You can build a simple network repeater in .Net using NetworkStream.
